You haven’t really talked about your unpleasant experiences
Be willing to have candid conversations about your insecurities, past traumas, your flaws and the uncomfortable things that will inevitably be uncovered.
It is scary to show vulnerability however, no one wants to be sidelined by major issues when their heart is already invested in a relationship.
Note, all of these things won’t reveal themselves in the first stages of getting to know a person but it should be something both parties are committed to talking about as time passes.
If you’re developing a relationship with a person and can’t seem to get past the façade, it may be time to re-evaluate that partnership.
